For various reasons, I'm need to move a ZCS install from ZCS 4.5.10 on Mac OS X 32 bit PPC to 6.0.5 Ubuntu 8 32 bit i386.
I've not been able to find a doc to denote if this is doable, or even a good idea.
Can anyone give any pointers other than copying the /opt/zimbra folder from the old server and trying an install? I was under the impression that settings needed to be read from LDAP which obviously could not be fired up due to the platform change.
I really have little choice here. If I have to, I'll resort to using IMAPsync, but I'd prefer to upgrade if possible.
